A servo-assisted power steering means is proposed in which one of the two track rod joints of the steered wheels is embodied as a linear force transducer. An electric or electronic switch is disposed in the tie rod or in the steering knuckle assembly and furnishes switching signals to an electric or electronic control device. These signals are then processed and supplied to a servo apparatus in order to reinforce the movement of the tie rod initiated by the driver via the steering wheel. The control device is part of a brake anti-lock apparatus, wherein the data pertaining to velocity which are required there are also used in the power steering in such a manner that the auxiliary force is switched on only in a low vehicle velocity range, so as to serve, for example, as an aid in parking of the motor vehicle.
